Product details
Overview
TLV2401IDG4 from Texas Instruments is a single-channel, rail-to-rail input/output micro-power operational amplifier with reverse battery protection up to 18 V. It delivers 880 nA supply current per channel, 5.5 kHz gain bandwidth, and operates from 2.5 V to 16 V supply. Its –0.1 V to VCC + 5 V input common-mode range enables use in Li-ion battery-powered sensor front-ends and low-voltage industrial monitoring systems.
For engineers reviewing the TLV2401IDG4 datasheet, TLV2401IDG4 pinout, TLV2401IDG4 application, or TLV2401IDG4 equivalent, this page provides verified specifications, package mapping to SOT-23 (DBV), functional role in ultra-low-power signal conditioning, and validated alternative options for battery-critical designs.
Technical Context
The TLV2401IDG4 employs a dual-differential-pair input stage-PNP-based for –0.1 V to VCC – 0.8 V operation and NPN emitter followers for VCC – 0.8 V to VCC + 5 V over-the-rail capability-enabling robust input tolerance without phase inversion. Its output stage supports rail-to-rail swing with ±200 µA drive capability into high-impedance loads.
Reverse battery protection is implemented via internal Schottky diode network, limiting reverse supply current to ≤50 nA at –18 V and 25°C. The device is specified across –40°C to 125°C (I-suffix), with DC accuracy anchored by 390 µV typical offset voltage and 120 dB CMRR at 25°C.

Equivalent & Alternatives
The following parts are listed as comparable options for similar micro-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2241IDBVR | 1 µA/ch supply current; 5 kHz GBW; no reverse battery protection; 0.6 mV max VIO | Lacks reverse polarity hardening; unsuitable for field-serviceable battery compartments | Choose when absolute lowest cost is prioritized and reverse voltage exposure is eliminated by mechanical design |
| LPV801MG/NOPB | 320 nA/ch supply current; 10 kHz GBW; no over-the-rail input; 0.25 mV max VIO; –40°C to 125°C | Higher precision but narrower input range (0 to VCC); no reverse battery or over-rail capability | Prefer when sub-millivolt offset dominates design requirements and input signals stay within rails |
Compared with TLV2241IDBVR and LPV801MG/NOPB, the TLV2401IDG4 uniquely combines reverse battery protection, 5-V over-the-rail input, and guaranteed 125°C operation-making it the only option for unattended, field-deployed battery-powered instrumentation where polarity errors or thermal extremes cannot be ruled out.

FAQ
What is the maximum reverse supply voltage the TLV2401IDG4 can withstand?
The TLV2401IDG4 supports reverse battery protection up to –18 V, with supply current limited to ≤50 nA at 25°C and ≤100 nA over full temperature range. This protects against accidental battery misinsertion in field-deployed equipment without requiring external protection circuitry. The internal Schottky diode network ensures safe operation even when VCC is reversed relative to GND, making TLV2401IDG4 ideal for maintenance-prone battery compartments.
Does the TLV2401IDG4 support true rail-to-rail input beyond the supply rails?
Yes-the TLV2401IDG4 accepts input voltages from –0.1 V to VCC + 5 V, enabling operation with signals exceeding the positive rail. This over-the-rail capability is achieved via an NPN emitter-follower stage that transitions to diode conduction above VCC, maintaining functionality without phase reversal. It eliminates external level-shifting components when interfacing with higher-voltage sensors or legacy analog subsystems, a key advantage over standard rail-to-rail op-amps.
What is the guaranteed operating temperature range for the TLV2401IDG4?
The TLV2401IDG4 is rated for –40°C to 125°C operation (I-suffix grade), with all electrical characteristics specified across this full industrial temperature range. This includes parameters such as 1500 µV maximum input offset voltage, 880 nA typical supply current, and 120 dB CMRR. The extended range qualifies TLV2401IDG4 for under-hood automotive, industrial control cabinets, and outdoor environmental monitoring where ambient temperatures exceed commercial-grade limits.
Can the TLV2401IDG4 drive capacitive loads without instability?
The TLV2401IDG4 maintains stability with capacitive loads up to 100 pF, exhibiting ≥60° phase margin and ≥15 dB gain margin under typical conditions (RL = 500 kΩ). For loads >100 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended. The device's low slew rate (2.5 V/ms) and low GBW (5.5 kHz) inherently limit high-frequency ringing, but layout best practices-including short traces, local 0.1 µF ceramic decoupling, and minimized input node capacitance-are essential to preserve stability in high-impedance sensor interfaces.
How does the TLV2401IDG4 achieve low input bias current at high common-mode voltages?
The TLV2401IDG4 uses a hybrid PNP/NPN input stage: a PNP pair handles –0.1 V to VCC – 0.8 V, while NPN emitter followers extend operation to VCC + 5 V. As inputs rise above VCC, the NPNs transition from active amplification to diode conduction, causing input bias current to increase-but remaining below 900 pA over full temperature range. This architecture preserves usable gain and linearity beyond the rail while maintaining picoampere-level bias currents required for megaohm sensor interfaces.
